Apple Developer Plugins

A marketplace of Apple-platform development plugins for AI coding agents, designed to work across Claude Code, Codex, and Cursor (and any agent hosted in cmux). Layout follows the openai/plugins convention.

Plugins

Plugin	Skills	What it does
apple-dev	ios-simulator-browser	iOS development bundle — mirror a running Simulator into an in-app browser and capture proof frames, or live-iterate SwiftUI previews from Swift packages with hot reload.

Install

Claude Code (marketplace — one-liner)

/plugin marketplace add jeonghi/Apple-Developer-Plugins
/plugin install apple-dev@apple-developer-plugins

Update later with /plugin marketplace update apple-developer-plugins.

Codex (marketplace)

Add this repo as a marketplace and install the plugin; the catalog lives at .agents/plugins/marketplace.json.

/plugin marketplace add jeonghi/Apple-Developer-Plugins
/plugin install apple-dev

Codex / Cursor / plain ~/.claude/skills (symlink installer)

If you prefer to install the skills directly (or your runtime doesn't consume the marketplace), clone and run the installer. It symlinks every skill in every plugin into each runtime's skills dir (so git pull keeps them current) and registers them in Codex's config.toml:

git clone https://github.com/jeonghi/Apple-Developer-Plugins.git
cd Apple-Developer-Plugins
./install.sh

Targets it links into when present: ~/.claude/skills, ~/.codex/skills, ~/.cursor/skills-cursor, ~/.agents/skills. Restart your agent session afterward.

Claude and Codex both load a plugin as a directory with a skills/ folder plus a manifest. Each plugin here ships both manifests pointing at the same skills/, so the one directory is a valid plugin in either runtime. Cursor just needs the skill directory on disk, which install.sh provides. cmux is a host, not a runtime: any agent inside it is covered by whichever skills dir it uses.
